Choosing correct size for Hormann and Garador garage doors and Front doors.
This page explains in detail how to choose the correct size garage door you require.
Choosing correct size for Hormann & Garador up and over garage doors.
- Garage door sizes are always stated as an internal frame size.
- Garage door sizes are always expressed with the width first and height second. For example door size 7’0” x 6’6” indicates that the door is 7’0” wide and 6’6” high. The exact internal frame size for this door needs to be 7’0” x 6’6”. The actual door panel will be approximately 18 mm smaller in width and height to enable a perfect fit with the correct tolerance gap between the door and the frame.
Are you purchasing a door to be fitted:
To an existing brickwork aperture?
To an opening which is being built to accommodate a standard size door?
To a new opening which cannot be built to take a standard size door for good reason?
Please see the relevant explanations for fitting methods 1, 2 and 3 below.
Purchasing a door to be fitted to an existing brickwork aperture.
Door with a pre-installed steel frame.
Please check your brickwork sizes with this PDF size chart
- For a BETWEEN BRICK FIT the brickwork aperture should be 10mm wider and 5 to 10mm taller that the stated EXTERNAL frame sizes.
- If the opening is bigger than this you can pack off and trim the gap with timber or UPVC if you so wish.
- For doors and frames being fitted on the BACK OF THE BRICKWORK APERTURE the structural opening should be at least 10 mm wider and higher than the stated internal frame size of the new up and over door. This is to ensure the door does not catch on the brickwork as it opens through the opening.
- Please check there is sufficient side room and headroom on the back of the opening to accommodate the frame size and any kick-up of the door.
Door fitted to a timber frame.
- If you are going to install the new door to an existing or new timber goalpost frame, the frame should be 70 mm x 70 mm in section, or larger. When measuring, please measure the internal timber frame size, not the actual door panel.
- The goalpost frame can sit between the opening or on the rear of the opening.
Purchasing a door to be fitted to a brickwork opening that is being built to accommodate a standard size door.
Decide whether you are going to fit the door and frame between the brick piers and under the lintel
or on the back of the brick piers
- If fitting on the BACK OF THE BRICKWORK APERTURE ensure you have neat solid brick piers, not brick-block or brick-cavity-block. If the piers are block work that is to be rendered or cladded after installation, allow for the thickness of this to ensure the door will be able to open out through the finished aperture. Fitting on the back of the brickwork gives more entrance width and height. When viewed from the front you can show 5 mm to 50 mm of frame.
- If fitting the door and frame BETWEEN THE BRICK PIERS AND UNDER THE LINTEL the brickwork aperture should be built 10 mm wider and 10 mm higher than the chosen external frame size.
